Well, that's a lot to digest. Thanks for all the info, Helen.

I looked closer at TIB_Cursor and used it to find the table names (as
you suggested). Looks like I can take the list of tables and prepare a
select for each and then use TIB_Cursor's Fields.Columns properties to
get each column's info and then each column's TIB_Column.BestFieldName,
SQLTypeSource, IsDateOnly, IsDateTime, and IsNumeric to get what I need.

Not too difficult. Just more complex than I expected. But it will get
the job done!
